About ATS plugin to read post data

[Rakesh Chhabra <ra...@gmail.com>]

Hi,

I need to write an ATS plugin where i need to get the post body and a few
request headers in the call. And based on certain condition i want to
return the OK response from ATS itself without forwarding it to any origin
server.

I went through null transform and few other plugin, where i can hold on
post data but not sure how can i get hold on headers, which generally i
access in remap plugin using
TSMimeHdrFieldValueStringGet.

Any hints will be helpful?

Thanks,
Rakesh

Rakesh,
Also I believe if you NEVER want to forward the request to the origin then
all you need is an Intercept Plugin, take a look at the C++ API as it makes
it pretty simple, but if you sometimes want to forward the request to the
origin based on the request body then take a look at my pull request.

I also have an open pull request :
https://github.com/apache/trafficserver/pull/351 that does exactly this, as
you've observed with transformations it's unable to block the downstream
connection and so this pull request exposes a new API to buffer the request
body before allowing the downstream connection to be established. The pull
request also contains sample plugins for both the C and C++ apis.

Ironbee does that, including both the basics and workarounds
for a number of glitches.  Might be worth taking something
from it as a startingpoint.
